To determine TERT promoter mutation status as well as the expression of PAX8, GATA3, p63, p40, p53 and uroplakin III in 17 patients with the upper urinary tract sarcomatoid urothelial carcinoma.
The aim of this study was to detect the deletions/duplication mutations in TP53 gene exons using multiplex ligation-dependent probe amplification (MLPA) method in the patients with transitional cell carcinoma (TCC).
This study was designed to investigate the association between TP53 mutation patterns and recurrence patterns in upper urinary tract urothelial carcinoma (UTUC) patients.
Taken together, our results provide evidence for RTK/RAS pathway activation and p53 deficiency as a combinatorial theranostic biomarker that may inform the progression and treatment of urothelial carcinoma.
The frequent presence of UroVysion FISH abnormalities, urothelial carcinoma in situ, and p53 positivity by immunohistochemistry in cases of urinary tract LELC suggests a similar pathogenesis to high-grade invasive urothelial carcinoma.
Inactivation of tumor suppressor p53 and pRb in urothelium by SV40 T antigen resulted in urothelial carcinoma, resembling human high-grade carcinoma in situ.
Between January 1999 and December 2008, 275 patients who received six BCG intravesical instillations for NMIBC (transitional cell carcinoma) after transurethral resection were assessed for differences in outcomes according to the level of p53 overexpression.
The aim of the present study was to investigate the effects of these two antineoplastic drugs on the apoptotic index and cell cycle kinetics of urinary bladder transitional carcinoma cell lines with wild-type or mutant TP53 (RT4: wild type for TP53; 5637 and T24: mutated TP53).
Alterations in p53 represent a highly promising marker of disease recurrence and cancer specific mortality after radical cystectomy for urothelial carcinoma of the bladder.
To determine the prognostic value of p53 gene mutations and P53 overexpression for predicting the incidence of recurrence, progression and long-term survival of patients with transitional cell carcinoma (TCC) of the bladder.
